“I am focused on the Nov. 6 election because too much is at stake for the people of Illinois,” Mendoza said in a statement at the time. “I’m considering a run for another office and have taken steps to prepare for that should I choose to move forward, but I have not made any formal decisions.”

The leaked clip caused a stir among Republicans ahead of the election. Mendoza's opponent Darlene Senger demanded Mendoza drop out of the comptroller race, as did lame duck Republican Gov. Bruce Rauner.

“Susana Mendoza’s Chicago mayoral campaign video is a prime example of her ... hypocrisy,” Senger’s campaign tweeted. “Running for two offices at the same time is unfair to Illinois voters, and I demand she drop out of the comptroller race immediately.”

Mendoza's first official mayoral bid video is titled "Future," and outlines several likely tenets of her upcoming campaign. The comptroller speaks to her upbringing in Chicago's Little Village neighborhood, on the city's southwest side, before her family felt the need to move away due to gun violence.

"No family should have to leave their city because their neighborhood isn’t safe,” Mendoza said in the video.

She also cites the city's high property taxes as an issue and emphasizes a need for strong education in Chicago public schools.
